Roof planes about did the trick. Nice tip. Thanks.

Sig added. Apologies. I don't have any photos that show the exterior detail as it's mostly below grade

I'm trying to show existing conditions on a home built in the early 19th century. The foundation is stacked stone and while basically plumb on the inside (at least for these purposes), the exterior slopes from about 12" wide at the sill to approx 36" wide at the base. Is there a straightforward way to show this in both plan and elevation?
